Nursing Elites

1. A nurse in a clinic is caring for a client who came to be tested for tuberculosis (TB) after a close family member tested positive. The nurse should know that which of the following is a diagnostic tool used to screen for TB?

• A. Sputum culture for acid-fast bacillus (AFB)
• B. Mantoux skin test
• C. BCG vaccine
• D. Chest X-ray

Correct answer: B

Rationale: The Mantoux skin test, also known as the tuberculin skin test, is a diagnostic tool used to screen for tuberculosis (TB). It involves injecting a small amount of tuberculin under the top layer of the skin on the forearm and then checking for a reaction within 48-72 hours. This test helps identify individuals who have been exposed to the TB bacteria. Sputum culture for acid-fast bacillus (AFB) is used to confirm TB diagnosis in individuals suspected of having active TB. The BCG vaccine is used to prevent severe forms of tuberculosis in high-risk individuals but is not a diagnostic tool. While a chest X-ray can show signs of active TB disease, it is not a primary diagnostic tool for screening purposes.

2. A client with chronic obstructive pulmonary disease (COPD expresses difficulty in bringing up bronchial secretions. Which action should the nurse take to help the client with tenacious bronchial secretions?

• A. Maintaining a semi-Fowler's position as much as possible
• B. Administering oxygen via nasal cannula at 2 L per min
• C. Helping the client select a low-salt diet
• D. Encouraging the client to drink eight glasses of water daily

Correct answer: D

Rationale: Encouraging the client to drink eight glasses of water daily is the most appropriate action to help with tenacious bronchial secretions in COPD. Increased fluid intake can help in thinning the mucus, making it easier for the client to cough up and clear secretions. This addresses the client's difficulty in bringing up bronchial secretions. Maintaining a semi-Fowler's position can aid in breathing but does not directly address the issue of clearing secretions. Administering oxygen may be necessary for COPD, but it does not specifically target the tenacious secretions. Selecting a low-salt diet can be helpful in managing COPD in general, but it does not directly address the client's current concern of clearing bronchial secretions.

3. During a home visit, a nurse sees a client with COPD receiving oxygen at 2 L/min through a nasal cannula. The client reports difficulty breathing. What is the priority nursing action at this time?

• A. Increase the oxygen flow to 3 L/min.
• B. Evaluate the client's respiratory status.
• C. Call emergency services for the client.
• D. Instruct the client to cough and clear secretions.

Correct answer: B

Rationale: The priority nursing action in this situation is to evaluate the client's respiratory status. When a client with COPD on oxygen therapy experiences difficulty breathing, the nurse should first assess the client's respiratory status to determine the severity of the situation. Increasing the oxygen flow without proper assessment can be harmful if not clinically indicated. While calling emergency services may eventually be necessary, it should not be the immediate action without assessing the client first. Instructing the client to cough and clear secretions is not appropriate as the nurse needs to evaluate the respiratory status before proceeding with interventions.

4. A provider is discharging a client with a prescription for home oxygen therapy. Client and family teaching by the nurse should include all of the following instructions except?

• A. Cleanse the mask or collar with soapy water every other day.
• B. Ensure that the straps on the mask are secure but not too tight.
• C. Apply petroleum jelly around and inside the nares.
• D. Post 'no smoking' warning signs at home in a prominent location.

Correct answer: C

Rationale: When providing instructions for home oxygen therapy, it is important to ensure safety and proper care. Choices A, B, and D are all essential instructions for the client and family. Choice C, 'Apply petroleum jelly around and inside the nares,' is incorrect. Petroleum jelly should not be used near oxygen sources as it is flammable and can increase the risk of fire hazard. Therefore, this instruction should not be included in the teaching.

5. A nurse is preparing for the hospital admission of a client who is suspected to have active tuberculosis (TB). Which of the following precautions should the nurse plan to implement to safely care for this client?

• A. Staff and visitors should wear gowns, masks, and gloves while in the client's room.
• B. The client should be placed in a private room with a special ventilation system.
• C. The client may be placed in a room with other clients who require droplet isolation precautions.
• D. The protocol for donning and removing personal protective equipment before entering or leaving the room of a client with TB is different than for clients who are in other types of isolation.

Correct answer: B

Rationale: When caring for a client suspected of having active tuberculosis (TB), it is essential to place the client in a private room with a special ventilation system to prevent the spread of TB bacteria to others. Choice A is incorrect because staff and visitors should wear respiratory protection, not just gowns, masks, and gloves. Choice C is incorrect as clients with TB should not be placed in a room with other clients, as they need to be isolated to prevent transmission. Choice D is incorrect because the protocol for donning and removing personal protective equipment for clients with TB is similar to other types of isolation, focusing on proper infection control measures.
